Why Big Bird is Good for Kids

Posted: 10/08/2012 8:17 am

Feeding my three-year-old picky eater grandson becomes much easier when I let him watch a few scenes from Sesame Street while he eats. But that's not the main reason for my defense of Big Bird and public television versus the commercial networks that Mr. Romney presumably prefers for children--no doubt in the spirit of free enterprise versus government support of quality television. The main reason is that an important research study has shown that Big Bird and his Muppet friends are not harmful to children's ability to think and focus, whereas some cartoons on commercial television stations are harmful to these abilities in children.

I am referring to a study that was published last September in Pediatrics, the official journal of The American Academy of Pediatrics, called "The Immediate Impact of Different Types of Television on Young Children's Executive Function." The study examines the effects of watching fast-paced cartoons on the attention span and memory of four year old children.

In this study, researchers divided 60 four year-olds into three groups. Each group was put into a room and directed to do one of the following activities: draw with crayons, watch a PBS show called Caillou, or watch a fast-paced commercial TV show called Sponge Bob. After nine minutes, the children took a battery of tests that required focus, concentration, patience, working memory, and manipulation. Researchers were hoping to capture the "executive function" of a child's brain with the tests.

The results of the study were remarkably in tune with what common sense has been telling us for years. Children who watched the fast-paced cartoons on commercial television did significantly worse on the attention and memory testing than the children in the other two groups. There was no difference in performance between the educational TV (Caillou) group and the group that had drawn pictures with crayons.

The researchers concluded that just nine minutes of viewing a fast-paced television cartoon had immediate negative effects on 4-year-olds' executive brain function. They issued the warning: "Parents should be aware that fast-paced television shows could at least temporarily impair young children's executive function."

So what was it about the fast-paced show that had a negative effect on the children's brains? What the researchers concluded was that the unnatural pace of the cartoon sequences was over-stimulating and stressful to the child's brain. The human-Muppet interactions on Sesame Street are naturally paced, whereas the Sponge Bob sequences were unnaturally rapid and the over-stimulation from the "surreal" pacing may have taxed the children's brains.

In an editorial in the same issue of Pediatrics, Dimitri Christakis, M.D., of Seattle Children's Hospital, writes that although the study was small, its results are nonetheless robust and critically important: "Connecting fast-paced television viewing to deficits in executive function, regardless of whether they are transient, has profound implications for children's cognitive and social development that need to be considered and reacted to... what makes programs good or bad has to do not only with the content itself but with what in communications research are known as the formal features of that content. Some sequences are naturally paced (eg, human-Muppet interactions on Sesame Street), and some are rapid (eg, Sponge Bob Square Pants). Others occur in what seems like slow motion (eg, Mr. Roger's Neighborhood)."

What does this study mean for parents who want to avoid having the executive functions of their child's brain impaired by television shows? It speaks to the importance for parents to focus on the quality of the various TV shows that are available for kids. The study strongly argues that parents should not allow kids to watch cartoons that are unnaturally fast-paced--the kind of cartoons that are readily available commercial television. If parents do not want to stress their child's brain, they should stick to PBS--and hope that Mr. Romney does not get the opportunity to obliterate it.
